Abstract: The present invention relates to the use of particulate materials as contrast agents in vivo light imaging.

Abstract: The present invention relates generally to wood-derived products and more particularly to products derived from treated wood and their use such as in bedding material for animals in various industrial, domestic and research applications.

Abstract: A method of spin forming, comprising the steps of: providing a tool having a first plurality of forming rollers spaced at a second plurality of distances from a spin axis; spinning around the spin axis at least one member of a set comprising (i) a work piece and (ii) the tool; and engaging the tool and a first end of the work piece. The method allows increased diameter reductions of a free end of a work piece in a single forming operation without collapse of the end of the work piece.

Abstract: A controlled deflection roll for forming a press with an opposed roll including an elongate tubular roll shell, an elongate support shaft extending longitudinally through the roll shell, and a fluid operated controllable load support means between the shaft and the shell, such as a piston with an open pressure hydrostatic oil interface facing the shell. The roll shell is constructed of a fabricated fiber reinforced matrix, and is comprised of a plurality of annular layers of fiber and matrix composite, so that the shell is of relatively light weight and has a reduced cross-machine bending stiffness.

Abstract: 3,7-Diazabicyclo?3.3!nonanes and selected derivatives thereof of the general formula: ##STR1## wherein Q=S; Z=CH.sub.2 ; and Y equals an N-acyl or N-alkyl group are disclosed as multiclass antiarrhythmic agents.

Abstract: A method for providing files to a remote node including the steps of determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, reserving bandwidth for the requested file if bandwidth is determined to be available, and opening the requested file for transmission only if bandwidth is reserved. In addition, an apparatus for providing files to a remote node including apparatus for determining whether bandwidth is available for transmitting across a communications link a file requested by a remote node, apparatus for reserving bandwidth for the requested file if bandwidth is determined to be available, and apparatus for opening the requested file for transmission only if bandwidth is reserved.

Abstract: A method is disclosed for reducing NOx pollutants in the combustion of hydrocarbon fuels in a two stage burner. A first stage of combustion is established and maintained passing a stream of combustion air and first stage products of combustion down a centerline of the burner to a second stage downstream therefrom. This second stage is established by arranging an array of fuel tips around the first stage burner, each fuel tip having a fuel jet with a nominal trajectory angled toward the burner centerline and an inert gas jet placed between the burner and the fuel jet which is angled to cross the trajectory of the fuel jet. Fuel is injected into the second stage of the burner through the fuel jet and the inert gas, e.g. steam, is injected through the inert gas jet such that it influences the trajectory of the fuel to a modified fuel trajectory which is moved away from the centerline of the burner.

Abstract: A session-oriented local area network (LAN) application and an ISO 8802-2 protocol driver code will cooperate in a new form of connectionless, session-oriented communication called Sideband. At each session start-up time, the LAN Application will communicate with the enhanced ISO 8802-2 based protocol driver on the local system and the LAN Application and the 8802-2 based protocol driver on the remote system to determine if they all support the Sideband. If Sideband is fully supported by both systems, Sideband will be activated for the session. To communicate on a session which has Sideband active, the LAN Application requests that data is to be sent using the Sideband. A check is performed to see if the data meets Sideband criteria. As Sideband is a connectionless medium, the additional code path needed to set up and track timers and to handle the resend attempts are saved in the protocol.

Abstract: A magnetic optical recording element including a rare earth-transition metal recording layer, a barrier layer and a self-passivating active metal layer.
